my fave is my warped board cut to fit the back of a cookie sheet...glued with contact cement so it is steady and flat now...inside the cookie sheet, i i put pc of cardboard, wrapped with old blanket and then covered with denim (my favorite ironing surface) ...then glued this all inside the cookie sheet...pin-able, ironable and cutable... and reclaimed a ruined board. I also have little ones for the end of my ironing board and inside my sewing kit.
